1. Q: What is the perimeter defense alarm system?
Answer: The perimeter prevention and alarm system is also called the perimeter anti-theft alarm system. It generally consists of four parts: the detection part, the signal transmission part, the alarm linkage part and the control part. After installing the perimeter protection alarm system in the fixed area that needs to be protected, When someone tries to cross the boundary around the protected area, the detection device on the boundary will send out an intrusion alarm signal after detecting the intrusion, and at the same time, the transmission part will send the intrusion signal to the alarm linkage part to prompt the relevant personnel to deal with it.
2. Q: What are the classifications of the perimeter security alarm system?
A: The current mainstream perimeter prevention alarms and similar products include six categories of electronic fences, infrared inter-radiation, vibration cables, electrostatic induction cables, traditional power grids and leakage cables.
3. Q: What is an electronic fence?
Answer: The electronic fence is a new type of perimeter prevention and alarm system, which has three protection characteristics of deterrence, blocking and alarm. According to different operating principles, the electronic fence products on the market are mainly divided into two types: pulse type electronic fence and tension type electronic fence.
Pulse electronic fence system: It is composed of the pulse electronic fence host and the front end of the pulse electronic fence. The pulse electronic fence host sends out safe high-voltage pulse electricity and transmits it to the front end (alloy wire) of the pulse electronic fence. The pulse electronic fence host monitors the pulse current by monitoring the pulse current. Whether there is a short circuit or an open circuit to determine whether an intrusion has occurred. When there is an intrusion, the pulse host simultaneously sends out an intrusion alarm signal to the alarm linkage device and the control device.
Tension electronic fence system: It is composed of tension electronic fence electronic components and tension electronic fence front-end mechanical components. The electronic component (detection module) of the tension electronic fence determines whether it is invaded by monitoring the change of the tension value of the mechanical component (tension wire - not charged) at the front end of the tension electronic fence. When there is an intrusion, the electronic component of the tension electronic fence (tension controller) simultaneously sends out an intrusion alarm signal to the alarm linkage device and the control device.
4. Q: Is the electronic fence safe for people and animals?
Answer: The pulsed high voltage generated by the electronic fence is high voltage and low energy. It has an electric shock effect on humans and animals, but it will not cause harm, and it will not be fatal. It only makes people and animals fear and stay away from the fence, forming a psychological barrier to achieve safe isolation and safety. purpose of prevention.
5. Q: Is the electronic fence very expensive?
A: The cost of electronic fences is not high, especially for the perimeter area with a large fence area, it is even 20% to 40% lower than the investment in installing metal mesh fences, and the protection effect is better.
6. Q: What are the advantages of electronic fence?
Answer: The electronic fence has the functions of blocking, deterrence and alarm, low false alarm rate (not affected by weather, small animals, branches, etc.), simple installation, long service life, and low comprehensive cost.
7. Q: What is the structure of the electronic fence system? What equipment and materials are generally included?
Answer: The electronic fence system is composed of a pulse host and a front-end fence. The pulse host is the core of the electronic fence system. It outputs pulse voltage and detects signals to the front-end fence. The front-end fence is composed of terminal rods, support rods, alloy wires, Fence net composed of insulators, warning signs, etc.
8. Q: Is the installation and operation of the electronic fence complicated?
A: The installation and implementation of the electronic fence system is very convenient. Design and install the implementation plan according to the terrain and configure the material list of the equipment and front-end fence, and install and connect according to the instructions. The average person only needs 2 hours to master the operation process.
9. Q: What daily maintenance and inspection are required for the electronic fence?
Answer: Basically do not maintain and check when the alarm is not issued, just regularly remove the trees and grasses close to the electronic wire of the electronic fence (although the weeds will wither and will not falsely alarm, but it will also consume some power).
10. Q: What is the application of electronic fence in foreign countries?
Answer: Electronic fences are widely used in developed countries such as Europe and the United States, and the usage is very high. my country is currently in its infancy.
11. Q: What is the service life of the electronic fence system?
A: If used and maintained properly, the electronic fence system can be used for 15-20 years.
12. Q: What determines the quality of the electronic fence?
A: Generally speaking, the quality of electronic fence products is mainly reflected in the stability of product operation, anti-interference ability, false alarm rate, repair rate and so on.
13. Q: What is a leaky cable?
Answer: Leaky cable is the abbreviation of leakage sensing cable, and it is also a perimeter intrusion detection system. The core device of the system is composed of a shallow buried intrusion detector on the surface of the cable and two leaky cables laid in parallel, which can detect and alarm moving metal objects, people and animals. Leaky cables are not only suitable for surface installation, but also for parallel wall installation.
